this time i had to fill out a questionaire for a consultation. at the end it simply said
"Thanks for your submission. We will be in contact with you by email shortly with our recommendations for your system."

so how do they know where to send the disc to if they never ask for an adress?

Okay, Paul McGowan at PS Audio got back to me. You need to contact Jackie Johnston at jackie@psaudio.com. All you need to give her is your address and she will send the DVD to you.
